Choose a hero to see his performance against other heroes

Lane winrate is determined based on networthes in the matchup at the end of the laning stage. Huge difference is won/lost lane, small difference is considered a tie. Won lane counts as 1 point, tie counts as a half.

Lane status of a support is based on a networth of the closest core (so if a support's core won the lane, the support is considered a winner too).

Rank for lane stats is based on lane winrate, number of matches, average differences in lane advantage and match win rate. In case of hero specific laning stats the highest rank indicates the best possible lane opponent to benefit the hero (aka the easiest one). There may be slight differences in numbers, produced by either lack of detailed analysis or lack of an opponent in lane.

There are some assumptions and only one factor used to detect laning outcome, due to my current limitations. HOWEVER, from practice it turns out to be pretty accurate with the real picture.

Since it's based on NETWORTH, it's naturally affected by hero and tower kills, as well as deaths. It also means that if a hero switched to jungle and got more from there, then the hero practically won the lane (if the hero didn't leave the lane completely).

Hero laning matchups are not limited to 1 vs 1 lane matchups. Supports and even multiple cores on lane may affect the picture.

There's no such thing as "lost lane 1 vs 3, but it's actually a won lane". If a hero lost lane, then the lane is lost, no matter how you call it. However, there are winrates from lost/tie/won lanes, that can show you, how effective the hero may be if the lane was lost, completing the picture. Same goes the other way around.
